Abstract
This invention is a film adhesive prepared from an adhesive composition comprising a polymer system, a film forming rubber compound, and curing agents for the polymeric system. The polymer system comprises a base polymer and electron donor and electron acceptor functionality.
Claims3
A rubbery film adhesive prepared from materials consisting essentially of:
- a rubbery polymer prepared from acrylic, vinyl, or conjugated diene monomers, substituted with both pendant electron donor and pendant electron acceptor functionality, and having a weight average molecular weight in the range of 300,000 to 1,500,000, and
- a free radial initiator;
- characterized in that the film adhesive can be cured within two minutes at a temperature below 300° C.
